Quality since 1983
1983 Roderich Ettlinger, a mechanical engineer by trade, founds the company as a manufacturer of plastic injection molding and customized machines.
1999 A new production shop opens to respond to the increased demand for ETTLINGER products.
2004 The first “ERF 200”, ETTLINGER‘s patented melt filter system, enters the market with immediate success.
2010 After 27 years steering the company’s success, Roderich Ettlinger makes way for his son Thorsten and Volker Neuber, who have since been responsible respectively for the technical and commercial development.
2013 ETTLINGER North America is established in Atlanta to serve customers in the U.S. and Canada with an efficient sales network, local technical services and rapidly available spare parts.
2014 The new ECO high performance melt filter for PET and the ERF 500 for throughputs up to 6,000 kg/h are launched in the market.
2015 ETTLINGER’s offices and production facility in Königsbrunn are extended and modernized as demand continues to rise.
2017 ETTLINGER presents the new ERF 350 melt filter as a further development of the proven ERF 250 technology.
2018 ETTLINGER joins MAAG Group, which is represented in the markets with its product brands AUTOMATIK, GALA, MAAG, REDUCTION and SCHEER.
2019 At the K 2019 trade fair in Dusseldorf, ETTLINGER unveils the brand new ERF 1000 high performance melt filter for throughputs of up to 10,000 kg/h.

High performance melt filters
Our continuously operating, high performance melt filters are used successfully around the world to filter polymer feedstock with varying degrees of contamination.
ETTLINGER melt filters are the perfect technology for processing a variety of recycled materials – with a patented principle that has already demonstrated its functionality and performance in many industrial applications throughout the globe. The ERF and ECO series are capable of processing virtually any standard polymer that occurs in recycling plants, sheet and film manufacturing, tape and fiber production, or the compounding industry.
Owing to their uniquely compact design, they are also ideal for retrofitting existing extrusion lines.

How they work
All ETTLINGER high performance melt filters are based on the same principle:
Melt flows from the outside to the inside of a continuously rotating filter drum with a large number of conical holes. The contaminants contained in the melt are retained on the outside filter surface; they are immediately removed from the screen by a scraper and then fed to the discharge system.
The filter drum and discharge system speeds can be adjusted independently of one another, so that in spite of the many possible applications the optimum setting can always be selected from both a processing and an economic perspective.
Benefits for you:
• Suitable for materials with up to 16 % by weight contamination• Extremely efficient filtration – including aluminum and elastomers• Constant process pressure• Short material and contaminant residence times in the melt filter• Closed system, no contact with outside air• Can run automatically for several weeks or months without changing the filter, depending on the application• Very low melt losses even with high contamination• Compact design with a small footprint• Automatic operation with high operational safety

ERF series
The continuous melt filters in the ERF series are suitable for materials with up to 16 % by weight contamination and are guaranteed to remain in use for long periods without changing the filter.
Our ERF melt filters are capable of processing a wide range of polymers (e.g. LDPE, LLDPE, HDPE, PP, PS, ABS, PC / ABS, TPE, TPU, POM). All solid or elastomer foreign particles such as paper, wood, aluminum, copper, rubber, silicone, or high-melting polymer composites are efficiently removed.
The classic application for ERF melt filters is repelletizing lines, but they are also successfully employed for sheet and profile extrusion. ERF melt filters can in principle be used in any extrusion line – either single or twin-screw and irrespective of the type of pelletizing system or other downstream unit. Four different sizes enable throughputs from 150 to 10,000 kg/h depending on the application.

ECO series
The continuous melt filters in the ECO series are equally suited for filtering polymer feedstock from industrial waste with a low level of contamination or lightly contaminated post-consumer waste, and they can also be used for clean virgin material.
Our ECO melt filters are capable of processing a wide range of polymers but due to their special design are mainly employed in PET and PA applications. All solid or elastomer foreign parti-cles such as gels, black specs, paper, wood, aluminum, copper, rubber, silicone or high-melting polymer composites are efficiently removed. In particular, there is significantly less degraded PET in the form of black specks.
For this reason, the classic application for ECO melt filters is extrusion systems, for instance where recycled PET bottle flake is converted into food packaging films, packaging tape, and fibers. PET repelletizing and compounding processes in general are other potential areas of use.
ECO melt filters can in principle be used in any extrusion line – ei-ther single or twin-screw and irrespective of the type of pelletiz-ing system or other downstream unit.
Three different sizes – ECO 200, ECO 250, and ECO 250 Twin – enable throughputs from 150 to 6,000 kg/h depending on the application.
